Diablo Steel Demon Cermet II, 7-1/4″, 48T TCG
This Diablo Steel Demon Cermet II blade is a benchmark for steel. The cermet-tipped teeth resist heat better than standard carbide. That means cooler, steadier cuts and fewer sparks. The 48T TCG grind supports smooth entry and exit on thin and medium-gauge metals.
On 7-1/4 inch saws, it strikes a smart balance of speed and finish. You can slice steel studs, angle, and even stainless plate with control. Chip size stays consistent, and the blade keeps its edge. If you want fewer burrs and less cleanup, this one makes a strong case.
Pros:
- Cermet II tips run cooler and last longer than standard carbide
- Clean, burr-light cuts on steel and stainless
- Low sparks and reduced discoloration on edges
- TCG grind stabilizes the cut and reduces grabbing
- Solid plate with vibration control for a smoother sound
Cons:
- Higher upfront price than basic carbide blades
- Not the fastest in very thick steel
- May still leave light burrs on ultra-thin sheet
My Recommendation
If you want the best circular saw blade to cut metal with a clean edge, start here. It suits remodelers, fabricators, and DIYers who cut a lot of steel or stainless. It runs cool on cordless and corded saws. You’ll spend more once, then save time on deburring and rework.
| Best for | Why |
|---|---|
| Steel studs and angle iron | Stable TCG and cermet tips make smooth, cool cuts |
| Stainless sheet and plate | Heat-resistant tips reduce bluing and keep tooth sharpness |
| Pros who cut metal often | Long life offsets higher initial cost |
DEWALT 7-1/4″ 16T Metal Cutting Blade (DW3330)
The DEWALT DW3330 uses a coarse 16-tooth layout for speed on thicker stock. It is a smart pick for cutting pipe, bar, and heavy studs. Fewer teeth mean bigger chips and a faster feed rate. The blade feels eager and strong through dense metal.
Expect a rougher edge compared to high-tooth TCG blades. But in structural cuts, speed often wins. This blade shines when you need a lot done fast. It is a budget-friendly way to gear up for ferrous work without overspending.
Pros:
- Fast on thick steel and pipe
- Strong tips for heavy-duty tasks
- Affordable entry to metal cutting
- Good fit on most 7-1/4 inch saws
- Reliable brand support and availability
Cons:
- Rougher finish with more burrs on thin sheet
- More sparks and heat vs cermet or TCG blades
- Not ideal for aluminum finishing
My Recommendation
This is the best circular saw blade to cut metal if you focus on thicker steel and speed. Framers and installers who chop through EMT, rebar, or angle iron will like it. It pairs well with high-torque saws. Finish work needs cleanup, but production cutting feels quick and sure.
| Best for | Why |
|---|---|
| Thick steel and pipe | Low tooth count feeds fast and resists stalling |
| Jobsite demo work | Durable teeth handle dirty material and nails |
| Budget builds | Lower price with solid performance |
FOXBC 7-1/4″ 70T Metal & Stainless Blade
FOXBC’s 70T blade targets thin metals and stainless with a fine finish. The high tooth count controls entry and exit on sheet stock. It reduces hanging burrs and saves time after the cut. The blade feels composed and steady in hand.
If you work with ducting, stainless trim, or thin-wall tubing, this fits. It will be slower in thick shapes. But it earns points for edge quality and control. For delicate metal work, cleaner cuts matter more than raw speed.
Pros:
- Very clean cuts on thin steel and stainless
- Reduced burrs and smoother edges
- Good stability at standard circular-saw RPM
- Less grabbing on thin sheet
- Consistent chip load for better control
Cons:
- Slower in thick steel or solid bar
- Needs a steady feed to avoid heat build-up
- Costs more than general-purpose blades
My Recommendation
Choose this if your version of the best circular saw blade to cut metal means a clean, polished edge. HVAC techs, auto fabricators, and kitchen installers will like the results. It shines where finish and accuracy count. The long-term payoff is less filing and faster assembly.
| Best for | Why |
|---|---|
| Thin stainless sheet | High tooth count and stable geometry |
| Thin-wall tubing | Smooth cut reduces deformation |
| Ductwork and trim | Clean edges reduce finishing time |
HARDWIN 7-1/4″ 48T Cermet Metal Blade, 5/8″ Arbor
HARDWIN’s 48T cermet blade aims to deliver premium heat resistance at a friendlier price. The cermet teeth hold an edge well under heat and friction. It pairs well with cordless saws that need clean, low-spark cuts. The 5/8 inch arbor ensures broad compatibility.
Cut quality is close to higher-priced cermet options with careful feed. It is a nice middle ground for pros and DIYers. You get smooth cuts on angle, channel, and plate. Vibration is minimal, and the runout feels controlled.
Pros:

In thick steel, feed slower and let the blade work. It rewards patience with straight cuts and smaller chips. For users who want neat cuts from a familiar brand, this is a safe bet. It plays well with most 7-1/4 inch saws.

The tooth count is high, so feed rate is moderate. But the finish is worth it on parts that show. Use wax or lubricant for smoother passes and less chip welding. If your work is mostly aluminum, add this to your kit.
Pros:
- Excellent finish on aluminum and non-ferrous metals
- TCG grind resists galling and chip welding
- Ideal for visible trim and extrusion cuts
- Works on miter and table saws as well

FAQs Of best circular saw blade to cut metal
Do I need a special blade to cut steel with a circular saw?
Yes. Use a metal-rated blade with TCG or cermet-tipped teeth. It runs cooler, throws chips, and reduces burrs. Abrasive discs work, but they spark more and wear fast.
What tooth count is best for steel?
Lower teeth (16–36) cut thick steel faster but rougher. Higher teeth (48–80+) cut thin metal cleaner but slower. Match tooth count to thickness and finish needs.
Can I cut aluminum with a steel blade?
You can, but it is not ideal. Use a non-ferrous TCG blade. It reduces chip welding and gives cleaner edges on aluminum, brass, and copper.
Are cermet blades worth it?
Often, yes. Cermet tips resist heat and keep sharp longer than standard carbide. They cut steel and stainless with fewer sparks and less bluing.
What safety steps should I follow when cutting metal?
Wear eye, ear, and hand protection. Clamp the work. Use a blade guard, correct depth, and firm support. Let the blade do the work and control the feed.
Final Verdict: Which Should You Buy?
The Diablo Steel Demon Cermet II 7-1/4″ 48T is my top pick. It delivers cool, clean, burr-light cuts with low sparks and strong life.
If you want the best circular saw blade to cut metal, match the blade to your material. Choose cermet for steel and TCG non-ferrous for aluminum.
